This mod removes police helicopters from the wanted system. It may not necessarily remove them from some story missions.

Requires:
Script Hook V: http://gtaforums.com/topic/788343-vrel-script-hook-v/
OpenIV: http://openiv.com/

As always, be sure to create a backup of your update.rpf (or any other files you intend to mod)

To install:
Run OpenIV
Go to update.rpf/common/data
Be sure to select "edit mode" at the top of OpenIV.
Right-click dispatch.meta and select replace.
Play the game.

Don't even try to use this online.
